I've had my eye on these Irish Moss drinks for a while now and I couldn't resist grabbing them from the international section at my local supermarket. Just seeing the word "peanut" on a canned beverage is intriguing enough, but the next question is: what exactly is this stuff? A smoothie? Protein or milkshake? Meal replacement? There is a clue on the front label written in small font, the word carrageenan.
